| Description of problem: Wild and Scenic River data near the headwaters of the Snake River appears to be slightly more closely aligned to topo map and aerial imagery then NHD data for the same river segment. GIS data for Wild and Scenic Rivers can be downloaded from http://www.rivers.gov/maps.html (http://www.rivers.gov/maps/gis/gis.zip) Note that the GIS data for wild and scenic rivers designated before 2000 in the same dataset is very inaccurate. Snake River Headwaters were designated 2009 (http://www.rivers.gov/wsr-snake-headwaters.html). |

| Description of problem: Errors in FCode designations. 13 quads in the 1:24k hi-res NHD dataset in western MT have all streams classified as perennial (FCode 46006) instead of differentiating between intermittent (46003) and perennial (46006). I've attached screenshots of the NHD features selected by both FCode 46003: http://imgur.com/06mzW and 46006: http://imgur.com/1VhdZ. The quads in question are: Felix Peak, Nimrod, Mount Bradley, Red Plume Mtn, Crescent Cliff, Quintonkon, Circus Peak, Horseshoe Peak, Capitol Mtn, Gable Peaks, Tin Creek, Porphry Reef, Mt Wright, Gates Park in HUC8: 17010207 and 17010209 |

| Description of problem: I monitor a feedback alias from ArcGIS Online users. Someone pointed out that "Lake Marion" is listed as "Lib Pines Lake" in our maps. We use the NHD in our topo maps, and staff indicates it's a problem with the data. We are working to correct our maps, but I wanted to share with you to correct in future distributions of the NHD. Thanks, Andrew |

| Description of problem: I am writing in regards to an error which I have come across while looking at topographic maps on the USGS website. In the quadrangle Canal Fulton, Ohio there was an old pond (prior to the building of the house on the current location in 1978) that was since been drain, but it still appears on the map in an area which is strictly residential lawn. The area is 40° 52' 42.84"N 81° 34' 23.41"W. Thanks you for your time and I hope this information has helped you in your reconstruction of your next map. Submitted for Billy Meismer |

| Sender information is not displayed. | ||
| Description of problem: Suggest that 15010015 and all adjacent subbasins in Nevada be reviewed for content regarding intermittent streams. An overabundance of intermittent streams in the area gives the false impression that the area is wet instead of dry as in a desert. These streams contain 46003 (intermittent) Fcodes when they should have 46007 (ephemeral) if they even should be shown at all. NHD content was recreated from old 7.5-minute maps which most likely were incorrectly compiled with too much empheral drainage. |

| Description of problem: Subbasin 01070004. The RC is 01070004000186. The problem is that the reach code it lies on extends to the main stem. The reach code needs to be either: 1. trimmed back to the trib (removed from the mainstem braid). In this case the mainstem braid would be given a brand new reach code. In this case the gage event would only need an update to the measure 2. eliminated from the trib (thereby only lying on the mainstem braid) and the trib then given a new reach code. In this case the gage event would need a new reach and measure. 3. completely removed and replaced by 2 new reach codes split between the trib and the mainstem braid. In this case the gage event would need a new reach and measure. |

| Description of problem: Los Angeles River incorrectly changes its feature code classification from Stream/River to Canal/Ditch at the 7.5-minute boundary between Canoga Park and Van Nuys quadrangles. Then the river changes back from Canal/Ditch to Stream/River at the 7.5-minute boundary between Los Angeles and South Gate. As per Hydrography Standards, "Do not capture rivers that have been channelized to control flooding or erosion, or to maintain flow for navigation as Canal/Ditch." The Los Angeles River should be coded as Stream/River for its entire length from origin (34.195, -118.602) to the Pacific Ocean. |
